Background and Objective:Thinqure20 is a polyherbal, reverse-pharmacology-based
formulation that contains Piper longum, Piper nigrum, Zingiber officinale, and rock salt as active
ingredients. It is designed to work as an effective antiviral agent and also as a preventive measure
against SARS-CoV-2. Clinical and non-clinical studies have established significant safety efficacy
and tolerability of Thinqure20 formulation in the treatment of COVID-19 infection.Methods:In vivo human study was conducted on COVID-19 patients for 5 days. A total of 30
Covid-19 patients (n = 30) were enrolled. In vitro, cell line studies were also carried out to evaluate
the potential effectiveness of Thinqure20 polyherbal formulation as an antiviral, antifungal, and Angiotensin-
Converting Enzyme 2 (ACE2) inhibition.Results:Human studies have demonstrated a mean percentage of reduction in viral load from baseline
to end of the study visit which was found to be 75.4%. The minimum and maximum reduction in
viral load was found to be 59.3% and 100%, respectively. Viral load testing was carried out by Reverse
Transcriptase-quantitative Polymerase Chain Reaction (RT-qPCR) test. In vitro studies of
Thinqure, 20 extracts showed potential antiviral activity against MS2 bacteriophage, influenza, and
human coronavirus, antifungal activity against Mucor racemosus, and significant ACE2 receptor
inhibition.Conclusion:Thinqure20, a polyherbal formulation, is a potentially effective antiviral agent against
non-enveloped viruses (MS2 bacteriophage), enveloped viruses (influenza and human coronavirus),
and antifungal agent against mucor strains. It is also proven to be effective in the treatment of
COVID-19 and can be attributed to an early recovery by the reduction in viral load.Clinical Trail Registration Number:CTRI/2021/03/032471.
